Do you know how to maintain a concrete mixer?

Concrete mixers are often seen in our daily production of building materials, bringing us a lot of convenience in the production of building raw materials. However, the maintenance of the machine is also very important. So, how to maintain the concrete mixer? Let's take a look together!

The concrete mixer should be placed in a flat position, with square blocks used to support the front and rear axles, so that the tires can be placed on the ground to prevent movement during operation. Regularly inspect the oil, circuits, and control equipment at each lubrication point, add lubricating oil as required, maintain the cleanliness of the machine, and remove dirt and obstacles from the machine. Before starting the concrete mixer, it is necessary to check whether all controllers are in good condition. After stopping, pour water and stones into the mixing drum for 10-15 minutes for cleaning, and then remove the water and stones.

The concrete mixer should implement secondary leakage protection. Before going to work, after the power is turned on, it should be carefully inspected. Only after passing the empty test run can it be used. It is prohibited to use a sledgehammer to remove the concrete accumulated in the concrete mixer drum, only a chisel can be used for removal. Before each shift, add water to the mixing drum and let it idle for 1-2 minutes, while checking the stability of the clutch and brake devices. The rotation direction of the mixing drum should conform to the direction indicated by the arrow. If it does not match the actual direction, the motor wiring should be corrected.

During the operation of the concrete mixer, it is necessary to regularly check whether the noise of the electric motor, reducer, and transmission gear is normal, and whether the temperature rise is too high. Regularly check whether the transmission clutch and brake are flexible and stable, whether the track pulley is in good condition, whether the wire rope is damaged, whether there are obstacles around, and the lubrication condition of various parts. After work and when the machine is not in use, the power should be turned off and the switch box should be locked. In the severe cold season, after work, the mixer drum should be cleaned with water and the accumulated water in the water pump, water tank, and water pipe should be drained to prevent the water pump, water tank, water pipe, etc. from freezing.

The above is the maintenance of the concrete mixer. Regular maintenance of the machine can not only extend its service life, but also increase its work efficiency, reduce the risk of accidents, and lower maintenance costs. I hope the above content can be helpful to everyone!
